Abstract (en)

A thermally conductive grease composition comprising (A) 100 weight parts of at least one base oil selected from liquid silicones, liquid hydrocarbons or fluorohydrocarbon oils and 500-1,000 weight parts of a thermally conductive filler mixture which is constituted of (B) an inorganic filler having Mohs' hardness of at least 6 and thermal conductivity of at least 100 W/m DEG K and (C) an inorganic filler having Mohs' hardness of at most 5 and thermal conductivity of at least 20 W/m DEG K, and in which the ratio of Component (C) to the sum total of Component (B) and Component (C) is from 0.05 to 0.5 by weight. <IMAGE>
